How do speakers work? (Read details)?

Question

I want to get started on a piece of artwork quickly to portray how such strange things are considered normal since we interact with them every day. So anyway, I need a quick but detailed explanation of the journey between the data leaving the audio device and the sound coming out of the speaker. If possible, the journey between the sound leaving the speakers and being interpreted by the brain too.

Any help is greatly appreciated, thanks!

Answer 1

Analog signal source to an amplifier to the speakers or digital signal source to a digital-to-analog converter (DAC) to an amplifier to a speaker to your ears.

You have an audio source. If the source is analong it may be connected to speaker directly or to an amplifier if it's not sufficient to drive a speaker by itself. If the source is digital it has to be converted to analog before being applied to a speaker. Sound that you hear is analog and speakers are analog devices. They have to be driven by an analog signal. A digital signal won't sound like audio if applied directly to a speaker. If you have a digital device, such as an MP3 player, the digital signal has to be converted to analog before it reaches the speaker.

There's a lot to describe the operation of a speaker. The analog electrical signal is AC or alternating current, not a DC or direct current. It goes to a coil mounted on the back of the speaker cone. This coil is on a form that is inside a slot in a powerful magnet. As the signal goes through the coil it generates a magnetic field. The polarity of the field is determined by the polarity of the signal applied to the coil. One polarity causes the coil to move inward and the other polarity causes it to move outward of the slot. The frequency of the AC signal determines the frequency of the cone movement. This movement causes vibrations or pressure waves in the air. Pressure waves are what are ears pick up and interpret as sound.

The pressure waves hit the ear drum or tympanic membrane causing it to vibrate. This in turn moves two small bones called the hammer and anvil. The anvil passes the vibrations to the stirrup which transfers the vibrations to a shell shaped, liquid filled channel that has small, hair like things called cochlea. Nerves connected to the cochlea created signals that are sent to the brain and are interpreted as sound.

Answer 2

The data in the audio device is translated into electrical signal via an amplifier. This signal travels down the wire to electro-magnets in the speakers. The electro-magnets vibrate and transfer this vibration to the speaker cone, which transfers the vibration to the air. When the vibrations reach your ear, your brain interprets them as sound.

Answer 3

Why do you wish to make use of complex phrases? As lengthy as we will be able to comprehend each and every different is it rather that main? Anyway, you might check out speaking with local English audio system in an effort to decide upon up one of a kind volcabulary. Reading books and looking films can be handy.
